Linux is the foundation of many operating systems like Android, Arch Linux, Debian Linux, Gentoo Linux, Ubuntu, Mandriva Linux, Pc, red hut Linux, Sabayon Linux, Slackware, and Suse Linux. Having dominancy in android OS smartphones, Linux has highly installed in the general-purpose operating system.

It was originally developed for Intel x86 computers but later, ported to other platforms as well.

Linux kernel was first released on September 17, 1991, by Linus Torvalds. Ubuntu was released on 20 October 2004 and it’s latest released version is Ubuntu 19.4 (18 April 2019). Many companies in the market make various Linux OS and core kernels with all components but the Linux kernel is developed and maintained by the Linux Foundation. They give special privileges to some highly qualified developers for being part of their free software foundation as Linux/GNU to build a better community. It provides all necessary components (tools, services and programs) for a fully operating system. It is the most-used OS for desktop and server applications. Linux is an open-source platform where users can download and modify its source code. Linux is a popular open-source operating system which is also referred to as the Linux kernel. Ubuntu has free software available for all and is funded through a portfolio of services provided by canonical. Hence Mark Shuttleworth decided to make a team of developers from the one established project Debian and create an easy-to-use Linux desktop: Ubuntu. Linux was already established in 2004, but it was not open source for every user. Linux has come with a lot of distros and its popular distribution is Ubuntu. Ubuntu and Mac are the second most common desktop OS after windows. In general, OS is software that allows users to run other application programs on a computing device. All major platforms (hardware and software) require an operating system.
